Pro Plan Veterinary Diets EN Gastroenteric Naturals Dry Dog Food
Verified Jun 17, 2026
This is a highly digestible veterinary therapeutic dry food designed to support digestive health in puppies and adult dogs, including large-breed puppies. It uses brewers rice and chicken meal as primary ingredients, with added pea and potato protein to reach a moderate protein level. The formula includes prebiotic fiber for gut microbiome support, coconut oil as a source of medium-chain triglycerides, fish oil, and antioxidants to support overall health while being made without corn, wheat, or artificial colors and flavors.
Nutritionally, this is a thoughtfully designed gastroenteric diet that provides moderate, easy-to-digest nutrition for dogs that need GI support, including growing large-breed puppies and adult dogs. The protein and fat levels are on the lower to moderate side, which can be gentler on sensitive digestive systems, and the inclusion of prebiotics, fish oil, and medium-chain triglycerides adds targeted support. It’s a strong option when a veterinarian recommends a GI-focused diet, though it does rely heavily on rice and plant proteins rather than being a meat-forward formula.

At a Glance
KibbleLab Review
Strengths
- Complete and balanced for both growth (including large-breed puppies) and adult maintenance, which is uncommon for many prescription GI diets.
- Formulated for high digestibility, with moderate protein (24% min) and fat (9.5% min) levels that are often easier on sensitive stomachs.
- Includes prebiotic fiber, fish oil, and coconut oil (MCT source), which can support gut health and overall wellness.
- Free from corn, wheat, and artificial colors and flavors, which can be helpful for some dogs with dietary sensitivities.
Considerations
- Chicken meal is the primary animal protein source, so it is not suitable for dogs with chicken allergies.
- A significant portion of the protein comes from plant sources like pea protein and potato protein, which may be less ideal for very high-protein needs compared to more meat-heavy diets.
- Brewers rice is the first ingredient, so this is a more carbohydrate-forward formula, which may not be necessary for dogs who do not have GI issues.
- Menadione (a synthetic Vitamin K source) is included; while commonly used and considered safe at regulated levels, some owners prefer diets without it.

Top 5 Ingredients Explained
01
Brewer's Rice
Brewer’s rice is a milling byproduct of rice processing made up of small broken white rice kernels commonly used in pet foods as a highly digestible carbohydrate source, filler and binder that provides readily available energy for dogs and cats while contributing little protein, fat or fiber. It is generally gentle on the stomach and cost‑effective, but diets using it must supply other ingredients for essential nutrients; pet owners should note its relatively high glycemic load (relevant for weight or diabetic pets), the potential for trace environmental contaminants associated with rice, and not confuse it with brewer’s yeast.
02
Chicken
Chicken is a common animal-based protein in dog and cat foods, supplying essential amino acids, B vitamins, and energy-dense fats that support muscle maintenance, growth, and overall health; for cats it also contributes toward dietary taurine but must be present in sufficient amounts or provided via supplementation. It is prized for its digestibility and palatability, though some pets develop sensitivities or allergies to chicken, and nutritional value and safety depend on ingredient quality and processing—raw chicken carries pathogen risks and whole bones can pose choking or GI hazards.
03
Brewer's Yeast
Brewer's yeast (deactivated Saccharomyces cerevisiae) is commonly used in dog and cat foods as a flavor enhancer and supplemental source of protein, B‑complex vitamins, trace minerals and immunomodulating components such as beta‑glucans. It can support skin, coat and general nutritional status, but may cause gastrointestinal upset or allergic reactions in yeast‑sensitive pets, is not a live probiotic, and should be used cautiously in animals prone to purine‑related issues or those receiving antifungal medications.
04
Cassava Root Flour
Cassava root flour is used in pet foods primarily as a gluten‑free carbohydrate and thickening agent, providing readily digestible energy and functioning as a binder in dry and canned formulas. It is low in protein and fat and provides few vitamins or minerals, so it is not a complete nutrient source; commercially processed cassava is generally safe but raw cassava contains cyanogenic compounds and its high glycemic index may be a consideration for pets with diabetes or weight management needs.
05
Animal Fat
Animal fat is used in pet foods as a concentrated energy source and palatability enhancer, and can provide fat-soluble vitamin absorption and essential fatty acids (including arachidonic and linoleic acids, depending on the source) that support skin, coat and overall cellular function—particularly important for obligate carnivores like cats. Because it is calorie-dense and prone to oxidation, fats are typically rendered and stabilized; owners should be aware that high-fat diets can contribute to obesity and may trigger pancreatitis in susceptible dogs, so quality, source, and total dietary fat should be considered.
